DRV8825 Motor Whining (RADDS)

  • Hello, I am new to RFF and am trying to install RRF on my custom designed IDEX 3D Printer. All of the motors are using the RAPS128 driver except for the extruders, which are using drv8825 stepper drivers. The two motors using the drv8825 drivers make a high pitched noise and dont move when i send the command for them to move. I have the things on the bottom of RADDS properly set for 1/32nd stepping, and I have checked all of the connections. The motors work with raps but not with the drv8825 driver. All motor currents are properly set for the current rating of the motor. I believe the issue lies in the configuration but im not totally sure. Are the drv8825 drivers compatible with radds and RRF in the first place. I have attached my config.g for reference. Thanks!

    I can't comment on the compatibility of DRV8825 with RADDS, but your E acceleration is 10000 which is very high. Try 1000.
